Located 1.5 hours south of Chicago, Space & Time is a peaceful respite in the country. Mastering sessions are generally unattended, but you are welcome to attend and get the full experience.
Engineer Jamie Carter does affordable mastering with Ozone 5 and Pro Tools 11, monitors on SLS S8R speakers while looking at trees and taking breaks to hang out with the goats. The price is $6 per minute of music (a 30 min album would be $180). The results can speak for themselves, so take a listen to some of these tracks too see if this is the right option for you.
